Arranged on said The operation of inyinvention is as follows: rock-shaft, and rigidly secured thereto, are a l The disks are in their normal position when pair of platforms, M, which are adapted to g the ciphers thereon register with the hands or pointers g. The weight S is secured on the scale-beam at the correct point to indicate the number of pounds of grain which constitute a bushel, or other predetermined unit of measure. It will be observed by reference to Fig. 2 that one of the platfornls M is closed against the bottom of the case while the'other platform is open, and that the valve Gis inclined so as to cover the upper end of the compartment having the open valve M. \V hen grain is poured into the hopper, it is directed by the valve G into the closed compartment, and the grain accumulates therein on the closed valve M thereof until its weight is sufficient to overcome the gravity of the scale-beam, when the valve at the lower end of the compartment opens and discharges the grain therefrom. As the said valve opens, the crank K of its rockshaft moves the link N so as to immediately close the opposite valve, M, and the motion of the link is communicated to the rod U, and through the same to the weight-lever so as to return the latter to its normal position and thereby cause the dog to move the units-disk a the distance of one tooth, and consequently register the fact that one bushel of grain has been weighed by the machine and discharged therefrom. The motion before described of the link N causes the rod V to partly turn the rock-shaft E so as to swing the valve G over the compartment the lower end of which has just been opened, so as to cause the grain to be delivered in the compartment which has just been closed, when the operation before described is repeated, and so on until a sufficient number of bushels of grain has been weighed.

It will be understood that at each complete rotation of the units-disk the tens-disk is moved the distance of one space, and that at the complete rotation of the tens-disk the hundreds-disk is moved one space, and thereby the registering device is read from all three of the said disks, thus a given number of hundreds, plus a given number of tens, plus a given number of units.

Having thus described my invention, I claim 1. In an automatic grain-weighing machine, the combination of the case having the vertical compartments, the hinge-valves in the bottoms of the compartments and having the cranks K, the link N, to which said cranks are connected, the valve G at the upper end of the partition between the compartments and having the crank F, the rod V, connecting said crank to the link, the weighted scale-beam O, and rod U, connecting link N to the scalebeam, substantially as described.

2. The combination, in an automatic grainweighing machine, of the case having the compartm en ts, the platforms or valves at the lower ends of the said compartments and having the cranks K, the link connecting the said crank, the scale-beam connected to and operated by the said link, the registering device having the ratchet-wheel a, and the dog X, pivoted to the scale-beam and engaging said ratchetwheel, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

CHARLES E. \VARNER.
